Flood insurance: the coverage your homeowners policy leaves out

About one in three National Flood Insurance Program claims comes from outside high-risk flood zones. Rain does not read maps.

The essentials

  • Standard homeowners insurance does not cover flood damage.
  • Flood insurance through the National Flood Insurance Program (NFIP) covers up to $250,000 for a home and $100,000 for belongings.
  • There is usually a 30-day waiting period, so you cannot buy it when a storm is already on the way.
  • About one-third of NFIP claims from 2013 to 2023 came from outside high-risk flood areas.

    Flood insurance is the policy most homeowners skip and later wish they had. A homeowners policy covers a burst pipe, but not water that comes in from outside after heavy rain, a storm surge or an overflowing river.

    Here is what flood insurance covers, where to get it, and how to time it so you are protected.

    What flood insurance covers

    Building coverage

    • Foundation, walls and floors
    • Electrical and plumbing systems
    • Furnace, water heater and built-in appliances
    • Permanently installed carpet and cabinets

    Contents coverage

    • Furniture and clothing
    • Electronics
    • Portable appliances such as washers and dryers
    • Curtains and carpets that are not built in

    Basements have limited coverage under NFIP policies. Finished basement walls, floors and most belongings stored there are generally not covered.

    NFIP claims from 2013 to 2023 that came from outside current high-risk flood areas

    Lenders require flood insurance for homes in high-risk zones with federally backed mortgages. Outside those zones it is optional, but flooding can still happen from heavy rain, poor drainage or snowmelt.

    Frequently asked questions

    Does homeowners insurance cover flooding?

    No. Standard homeowners policies exclude flood. You need a separate flood policy.

    How much does flood insurance cost?

    It depends on your home's flood risk, elevation and coverage amount. A home outside a high-risk zone often pays much less than one inside it.

    Can I buy flood insurance anytime?

    Yes, but NFIP policies usually take 30 days to start. Buying when a storm is forecast will not protect you from that storm.

    Does flood insurance cover my basement?

    Only partly. NFIP policies cover essentials such as the furnace and water heater in a basement, but not most finished areas or stored belongings.
